RC Dozer Build

WELL DONE..!! thanks for posting

Best home Made.. Really simpel..! I like this..! Tomorrow, i try make it

Your use of what looks like a bicycle chain is a good idea, and what you have so far is well made. I would suggest adding a spring tensioner on the dozer tracks - an idler with spring loading would work fine. I have a Struck Magnatrac (mini dozer) and the front sprocket has an adjustable spring tensioner on it. Some use bogey wheels with spring tension (also can add a bit of resiliance to the dozer and make for a smoother ride). The right-angle grousers (name for the 'shoes' on the track chain) are interesting (my mini dozer has add-on channel grousers and they REALLY add to traction, but can tear up the lawn). I've seen grousers that were angled so that when flat, they overlap each other slightly. That helps to keep crud and so on out of the gears and chain. I'm curious as to how it all turned out.

Had to leave my comment. Loved the idea, was looking all over YouTube, found a Brazilian that had a similar ideia but yours is much better concept. Will put this information to good use :)

very cool your track good idea

Ok thanks! I really like you videos.

I would be interested in seeing what ya come up with! Be sure to post a video or two if ya can.....good luck man!

Very good

I had to make the little "L" brackets and it came in 4 foot lengths. It attached to the chain and to the track pad. I have had rocks get in between the tracks but has no problem breaking them. So its not a issue at all.

I did... Its made out of 1 inch square tubing... then cut the 1/8 inch flat bar into the shape for the road wheels, welded one side, then bolted the wheels to another identical piece.

@Tepsija20 Thanks, The motors them self have quite a bit of tourqe...I wanted just a bit more so thats the reason behind it. The model is 100lbs, so most of the power from the motors when into moving it. When it came time to push somthing the combination of the weight of the dozer and the pushing of the load was quite a bit for it. After I did the mod, it showed a big improvment. I would recomendgetting the most out of your motors by adding gears! Good lucK, and post vids.

I bought 1 1/4 inch flat bar from Lows, cut it up into 2 inch peices, bent 1/4 inches up to give it that "L" shape. Drilled holes and attached it to the little "L" shape peices then to the track (chain).

tq very much for your video...

haaa haa nice dude.same as like mine idea? but like it very good job

what about the pad connection to chain? you were using some side plates? do you get rocks and debris sruck between the pads? they get quite spaced aapart running over idler wheels?

wow long name and thanks and what gear set up did you use on your dozer

@Warrioryz125 check out the Sabertooth motor controls. I used the 25x2 for the DC drive motors (car window motors or wiper motors either or) for each track and used the 2x5 for the linier acuators for the blade control. They each rin from the radio receiver. Check out my video on the set up, under dozer rebuild.

@mr7sounder I have little under $1000. Big cost items, DC window motors $50 x2, 8ft hollow pin chain $100, Liner Actuators $90 x 2, Radio and Servos $150, steel, nuts and bolts..around $100, 4x wheels $50, sprockets 2x $25. Bought the steel, nuts/bolts at Lows/Home Depot, ordered chain, sprockets, wheels from Mc Master Carr. Motors from robot market place, liner actuators from E motion LLC. Bought radio w/ servos from a hobby store.

they are 12V car window motors or wiper motors either or. I found them at (Search) Robotmarketplace. They have bigger or smaller motors as well.

@1goldenclaw You will have to search: Blade actuators from E-Motion LLC, Robot Market Place for motors, McMaster-Carr for chain, sprockets, and belt pulleys (wheels) and Dimension Engineering LLC for electronics drive and blade motor control. All steel and hardware was purchased at home depot/ lows. Radio and receiver at local hobby store. Its all DC 12 V power, currently use a rechargeable Power wheels battery from Wal-mart.
